mg_spline.pro
Creates a 2-dimensional spline curve through the given x- and y-coordinates.
Examples
A spline curve through some points can easily be computed:
IDL> pts = mg_spline([1, 3, 5], [1, 5, 3])
IDL> plot, findgen(11), /nodata, xstyle=9, ystyle=9
IDL> plots, pts
IDL> .run mg_spline
Other file information
- Todo:
this should break down segments so that the x passed into SPL_INTERP is always monotonically increasing
Routines
top mg_spline
result = mg_spline(x, y [, n_points=long] [, _extra=keywords])
